Abstract

Purpose:
Lumbar extension syndrome is one of the types of mechanical back pain. Repetitive movement or postures are one of the main causes, which makes problems and disorders in people. Various interventions have been mentioned to improve the symptoms of people suffering from back pain, however, limited studies have investigated lumbar extension syndrome and the effect of exercises on it. Therefore, the aim of this study was to compare the Effects of Eight Weeks Sahrmann Stabilization and Postural Restoration Institute Exercises (PRI) on Disability, Breathing Function, and Motor Control of Patients Afflicted by Lumbar Extension Syndrome.
Methods:
In this semi-experimental study, 22 participants with mechanical lumbar extension syndrome have been tested by a specialist and were selected as available, and after the description of the study process and the approval of the subjects, they entered the study. After that, they divided into two groups matching, Sahrmann stability (Mean ± SD age: 51.5±6.12 years, height: 168.7±4.7 cm and weight: 74.4±9.3 kg) and PRI (Mean ± SD age: 51.1±6.2 years, height: 168±2.2 cm and weight: 75.4±9.7 kg) groups. Each group did the exercises for eight weeks and three sessions a week. Each training session took 45 minutes. Degree of disability (the Quebec Back Pain Disability Scale; QBPDS), breathing function (the Self Evaluation of Breathing Questionnaire; SEBQ ), and motor control (the Luomajoki test) were evaluated before and after the exercises. The data were analyzed using the statistical method of the correlated T test and analysis of covariance (p<0.05).
Results:
The data shows that there are significant differences between the mean of breathing function of two groups of Sahrmann stability exercises (before 16±4.5 and after eight weeks 10±3.6); With PRI exercises (before 16.8±2.5 and after eight weeks 7.7±3.7) there are people with lumbar extension syndrome (p=0.023). Also, there are significant differences between the mean of motor control of the two groups of Sahrmann stability exercises (before 4.2±0.87 and after eight weeks 4.9±0.94); With PRI exercises (before 3.8±0.87 and after eight weeks 5.5±0.93) there are people with lumbar extension syndrome (p=0.004). However, there are not significant difference between the mean of disability of the two groups of Sahrmann stability exercises (before 55.2±13.8 and after eight weeks 30.2±13.2); With PRI exercises (before 55.9±12.7 and after eight weeks 27.5±12.9) there are no people with lumbar extension syndrome (p=0.389). Therefore, the PRI group (breathing function 54%; motor control 44%) improved more than the Sahrmann stability training group (breathing function 37%; motor control 16%).
Conclusion:
As can be seen, both Sahrmann stability and PRI exercises have good results on disability, breathing, and motor control in patients afflicted by lumbar extension syndrome, but due to the specificity of PRI exercises according to postural patterns and also the importance of the diaphragm as a vital muscle for local stability, PRI exercises can have better effects than Sahrmann stability exercises.
